Tips on helping to dilate further!!

Heather
I'm currently 35+4 with identical boys, I've been 2cm and 70% effaced for almost a week now, I've been having irregular contractions for a few weeks now, pressure in my booty and vagina, and I've lost pieces of my mucous plug yesterday and today, I've had both steroid shots, I'm ready to get these guys going!! My doc says she's comfortable with them coming any day! Any thought of tips on helping me progress??
**yes I know the longer they're in, the better, but they are measuring ahead in both weight and length, so please!! only helpful comments only!!**
